A smoke catcher for welding fume

Abstract

The invention relates to a smoke gathering plate for welding smoke. The smoke gathering plate is characterized in that the smoke gathering plate is hollow so as to constitute a smoke gathering cavity, and strip-shaped smoke gathering square holes are formed in the inner side face, facing the welding operation side, of the smoke gathering plate. The smoke gathering cavity is gradually narrowed from the near to the distant along the side edge of the smoke gathering plate. The smoke gathering square holes close to the far end of the smoke gathering plate are provided with smoke guide fins, and the smoke gathering square holes close to the near end of the smoke gathering plate are not provided with smoke guide fins. The welding smoke generated by a welding workshop is gathered in time, and the smoke gathering plate is high in gathering rate, complete in gathering and especially suitable for gathering the welding smoke of a large-range workshop.

Description

technical field [0001] The invention belongs to the technical field of welding fume treatment, and in particular relates to a fume catcher for welding fume. Background technique [0002] In the field of modern industry, the welding of metal materials is one of the most basic and common structural parts processing procedures. With the rapid development of welding technology, the harm caused by welding fume (welding fume) to the environment and welding operators has gradually caused people's attention. During the welding process, a large amount of welding fume is produced, which pollutes the working environment. Especially in the case of poor ventilation, the dust concentration usually exceeds the national standard several times, which can cause welder pneumoconiosis, manganese poisoning, respiratory inflammation, neurasthenia, etc. occupational hazard. [0003] At present, there are two main methods for collecting and processing welding fume: one is to carry out overall ven...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two main methods for collecting and processing welding fume: one is to carry out overall ventilation in the welding operation area of ​​the workpiece to collect and process the smoke. large, high energy consumption, and unsatisfactory smoke removal effect; the other is to use a point-to-point method, that is, to collect and process the welding fume generated by a single welding point with a small exhaust port, which requires a small amount of exhaust air , has the advantages of flexible use, convenience, energy saving, etc., but it is not suitable for welding large workpieces. It is only suitable for small-scale local welding fume removal, and cannot adapt to large workshops and long workpieces.
